How to change a transaction date

Good afternoon,

I have been setting up a client in Sage Business Cloud Accounting by importing their bank statements from the day they started trading. Their first VAT return was filled through another system. I created an income transaction from a payment received on the 5th April 2022 but the tax point of that transaction is March 2022. VAT has been accounted for that transaction and already paid. Is there a way to change the tax point of that specific transaction so that the next VAT return does not pick it up? 
Many thanks for your help,
